论文摘要

在这项贡献中,我们报告了我们在Chara阵列中增加密歇根州红外联合仪(MIRC-X)仪器的光谱范围的工作,以允许进行双H和J带干涉测量值。我们评论该项目背后的关键科学驱动力,以及对辅助双折射和分散的表征和纠正的方法。此外,我们还报告了2019年11月在天上委托的第一个结果。

In this contribution we report on our work to increase the spectral range of the Michigan Infrared Combiner-eXeter (MIRC-X) instrument at the CHARA array to allow for dual H and J band interferometric observations. We comment on the key science drivers behind this project and the methods of characterisation and correction of instrumental birefringence and dispersion. In addition, we report on the first results from on-sky commissioning in November 2019.
